Forepart lasting machine

Forepart lasting machine is an important machine in shoemaking in the Quality shoe production house.  It is also known as toe lasting machine. It improves the quality of lasting operation and reduces time. So for mass production, it is an essential machine.

The following parts of forepart lasting machines are given below…………..

1 Treadle: It is the controlling device of the operator. Up to gripping of the toe pincer, the operator can forward and backward the forepart lasting operation by a treadle. There are different steps in the treadle. A skilled operator can control the treadle operation very well.

2. Insole rest: After attaching insole and putting upper on the last, the last is placed on the insole rest before starting the treadle operation. The size of the Insole rest is different for different series (Like Children, Boys, Girls, and Gents) and shaped last.

3. Pincers: There are normally 7 pincers and 9 pincers forepart lasting machines are available in the Indian market. The numbers of pincers should be odd digit because in every machine there should be one toe pincer and rest pincers are divided into two equal groups and arrange in both inside and outside of the last. After starting a treadle operation toe pincer grip the toe portion of the upper and pulled it over the last. If the operator sees the position of the toe gripping is right then he continues the operation. Then other pincers grip the total forepart upper and pulled it over the forepart of the last.  The sizes of the pincers are different for different series (Like Children, Boys, Girls, and Gents) and shaped last.

4. Toe hold down: After pulling the upper over the last by pincers toe hold down to fix the last position so that the last cannot move in the upward direction.

5. Applicator: A Holt melt adhesive comes from the applicator in a liquid state and spread over the edge portion of the forepart of the insole. There is some type of heating arrangement in the nozzle to heat the hot melt adhesive and make it liquid from a solid state.  

6. Wiper plate: After adhesives come over the edge portion of the insole, the pincers just lose the grips and wiper plate wipes the edge portion of the upper over the edge portion of the insole. And hot melt adhesives again solidify and thus the edge portion of the upper remains fixed over the edge portion of the insole.

7. Hydraulic device: The forepart lasting machine’s main operating force comes from the hydraulic pressure.  There is a hydraulic chamber which is filled by Hydraulic oil of specific density.

8. Safety Switch: It is used for emergency stop of the machine to prevent accident or and damages of the upper or machine. It is generally mentioned by the red color.

9. Control Panel: Pressure, time of operation temp of application can be controlled by digital or analog control panel.
